Re: What does !time mean in mugen?

Time = -1 occurs in the transition between two statedefs. This is a basic example:

Assume you have Statedef x, Statedef x+1 and Statedef x+2. And assume you have the following flow of states:

GameTime       State

Y                      Statedef x [on-screen]
Y+1                  [change state] Statedef x+1 => [change state] Statedef x+2 [on-screen]

What I wrote above means that the character went through two changestates in frame Y+1. However, it does not mean that Statedef x+1 did "not exist", as you can write logic inside and it will still be processed (as otherwise, statedef x+2 would not be on-screen at all). Some logic within statedef x+1 is evaluated in time = -1, particularly all triggers of the absolute form trigger1 = 1 (always true). You can actually observe "time = -1" written in displaytoclipboard by cleverly using pauses and targetstates. If that state transition is stretched way beyond the scope of one frame, all of that transition is time = -1.

Most people write trigger1 = 1 when they mean trigger1 = time >= 0 or even time > 0. These triggers are not equivalent and the malformed trigger1 = 1 will always be erroneously evaluated during state transitions.

This is part of the reason the physics in common1.cns are broken. I patched this when I released Angel many years ago.

Hello, how you are? !Time mean Time <= 0 (also it's Time = 0).

This is incorrect. It means "time" is not true, and this is if and only if it attains no value other than 0. So "!time" and "time = 0" are equivalent.

"time <= 0" is NOT equivalent to "time = 0" because "time = -1" exists, and it is a real state-time where malformed triggers (such as trigger1 = 1) are evaluated.

or is it that the character itself is badly coded?
I don't think it's the latter since everything works fine when he/she is on their own.

Badly coded is the correct term. A helper is essentially a complete clone of the character in terms of memory strain on the engine. If a character is constantly hitting the 56 helper limit, then there is a serious optimization problem.

Lack of proper helper optimizations is common, especially with the advent of faster computers. In winmugen days it was enough to spawn / respawn a set of 2 or 3 helpers in quick succession to slow down the engine on Haswell quad cores (which were top of the line computers at the time). If you wanted your character to not lag the engine, you had to get creative about optimizing the effects you were trying to produce.

OK, please hear me out:

- Back in the early 2000s we were supposed to post the Author's website, where the download link could be found. Authors would have VISIT COUNTERS (clout?) and these days they even have PATREON and PAYPAL Links. How is this "Visit my Youtube channel!" any different?

I agree with this position.

YouTube is now a modern equivalent of a blog for many people. It should be treated like a regular website. Youtube is free and the information posted in it will never go down, unlike privately hosted websites.

Hello, I am posting here because I don't know where to post this.

One of the this guy's GIFs in his signature is a ridiculous 1.5 mb, and the signature itself is huge.

I hope I do not need to comment on the fetish nature of the avatar.

https://mugenguild.com/forum/profile/ryou-75836

This signature is over 300 kb and arguably not safe for work:

https://mugenguild.com/forum/profile/arcbeast-92153

This signature is over 400 kb and the entire profile is something I would not categorize as safe for work either (he speaks about sex without a condom, really):

https://mugenguild.com/forum/profile/dead-or-alive-fan-5995

This one is safe for work, but the signature is HUGE and a ridiculous 600 kb:

https://mugenguild.com/forum/profile/capricorn-kid-87907


If the forum rules are no longer having a profile with a total data load under 250 kb, can the rules be updated to reflect this?

I am also not sure what the policy is on what type of content is allowed on profiles, but recently there have been profiles using avatars /  signatures with content which frankly makes me uncomfortable (see above).

I fully understand the desire of people wanting to share cool stuff they like in their profiles, but I am afraid we are hitting a moment in time where rules have to be made clear in what is okay to put, and what isn't. It makes the forum unnecessarily heavy to load because of an animated GIF of anime.

Loading one page of Guild (with all of the signatures above) far exceeds the size of one well optimized MUGEN character.

I only had a look through the video, and the combo system looks like something that I can only best describe as "spaghetti".

My recommendation is to spend a little more time and care in programming the behavior. There is still plenty of work to do to get him out of the oven, the character is substantially "under-cooked".

I heard that N-Mario already have the template of Hyper Street Fighter Zero but when I check upon it, it lacks the guard power gauge which is essential in the game's uniqueness.

In addition to a proper V-ISM mode.

Street Fighter Zero 3 V-ISM is the last remaining major open problem in MUGEN. It requires a handful of very sophisticated techniques and tricks to work.

Producing one proper template character would take roughly the same amount of effort as making 20 improper ones using this template. These are most likely the hardest characters to make right now. Perfect for a younger generation.  :)

MUGEN uses its proprietary scripting language. The Ghidra provided "source" is C++ I believe.

Either way, it is a complete waste of time for a professional. It is known that the MUGEN source code is already bad, but looking at it with zero labels makes it a nightmare to navigate. Efforts are better spent programming for next-gen engines like Blugen or Ikemen GO.

Hi Vans,

Dear Karma,

Thank you for your kind words. A good friend informed me about your post, and only now I am able to find some free time to reply to you.

That problem you show is indeed a bit odd. I only had a brief moment to look at your post and videos, and the only thing I noticed is the out-of-the-norm design of the hitboxes in your Whirlwind Slash projectile. Traditionally, Capcom and SNK projectiles use a bigger contact (CLSN2) box, which completely encloses the attack (CLSN1) box. However, I believe in your example this behavior is reversed, your attack box envelops the collision box, so this projectile design is non-standard. Some examples (Hotaru, using KOFXI boxes and Sagat by Jesuszilla, using CvS2 boxes):



I am not 100% sure if this is the cause of your problem, but it is what I could notice immediately.

I am afraid that without direct access to the characters I cannot make any further diagnostics.

You can find me on discord as Vans#9119. Please, do not hesitate to contact me if there are any more questions or comments.


Sincerely,


Vans.
    

Re: Buffering issue in turn state?

DeathScythe said, September 25, 2020, 05:09:17 pm
This is a known bug in MUGEN, direction inputs are a mess. Fortunately, yes, there are work arounds for this, but is not that simple. I suggest you to look here:
http://mugenguild.com/forum/topics/fix-all-your-command-issues-explodsive-buffering-system-180772.0.html
IMO the best work around, It may look confusing and intimidating at first but if you read everything carefuly you'll see it's easier than it looks.

You don't need to do all of this if all you want to do is fix the reversed commands bug.

The reversed command bug happens because of the following reason: MUGEN has a command parser which continuously begins to read your joystick inputs (e.g. B,DB,D,DF,F etc) relative to your facing.

Notice how above the command actually say "back" and "forward" instead of joystick "left" and "right". This is because the command parser in MUGEN is relative to your character's facing. So if you want to input something like "D,DF,F", and your facing becomes flipped (for any reason, such as the opponent jumping over) then the detection will be broken.

Assume the following scenario: the opponent jumps over and your character's facing becomes flipped in the frame where you press "F" in the command you want to do. To the parser, it looks like you did "D,DF,B" as an input. Again, because it doesn't detect pure joystick motions, only ones relative to your facing. I already wrote about this: https://mugenguild.com/forum/msg.2365602

How to solve it:

1. You need an object that doesn't have the parser modified relative to its facing. So an object that cannot turn. Once you have this object, you can detect commands off of it.
2. You need to manually detect two versions of the joystick motion, the one facing left and the one facing right. The object above is now able to accurately tell you which motion was performed in the joystick, it is now your job to decide when you use a specific version at the appropriate time.

To fix it:

1. Create a helper with the keyctrl = 1 flag enabled (to detect commands). Make sure this helper cannot turn. Assume its number is 10971 for the purposes of my example.
2. If you want to detect a fireball like QCF, please make two copies of the command in your .CMD, one is facing right "QCF" and one is facing left, "QCB". You need both.
3. In your Statedef -1, now you need to detect when it is appropriate to use each version of the command. Your trigger would look something like this:

Code: 
triggerall = cond(p2distx, (helper(10971),command="QCF"),(helper(10971),command = "QCB")) 

You shouldn't have problems while doing the motions any longer, because the reference point (the helper) no longer turns. This makes the parser accurately detect joystick motions.

I hope this helps.

Nothing too fancy here, the reference code is pretty much unchanged from the original PotS Ryu. The statedef is 0, and unless you're doing this with some obscure character made by some madman living on a mountain, is always the same. This is the code I'll be putting

I don't mean to sound rude, but I think you should refrain from such statements.

Hello!

Thank you so much for your report, I really appreciate it.

I am very sorry about this, I am guessing this is "Iori_RW". He is indeed incomplete, I was programming a new patch for my Iori to bring him up to the same standard as Xiangfei, Hotaru, Jenet, etc. Sadly, I have not finished it yet.

I have moved this archive to the "Beta" section, and uploaded what I believe to be the original archive of Iori_LB. I hope this one works fine.

I am very sorry about this.

By the way, I am also reachable on Discord via Vans#9119. Please feel free to contact me if there's any more questions or comments that maybe don't need to go in the topic.

Dear Ryou Win,

I watched the video of your new character Jiban when you posted last Friday, and was hoping to leave you a comment earlier. I expected someone else to comment before I did, so I am surprised your release doesn't have as much exposure as it should.

I wanted to mention that your video brought a big smile to my face, this is one of the most creative works to have graced the engine for quite some time. The amount of care and attention that you put into every single detail is very remarkable. I believe that your game project resembles some of the late 90s digitized "indie" fighting game titles that exist in Japan, and I have no doubts that a full game in this style would prove very popular with fans of this style of game.

Big congratulations friend.  :)
